Experiment with Color & Liquids

If you add a drop of food coloring to a glass of water, the food coloring
mixes into the water. If you add a drop of oil to water, the oil will
not mix with the water. Now place a drop of liquid detergent on top of
the oil drop, and the oil drop practically explodes into the water.

Try this experiment of adding colors to a pan of milk and add detergent
to watch a colorful display
